Disney Marathon - Goofy Challenge

Full Marathon at Disney World. I knew it was going to be a long day as I was already getting tired by mile 6. Thoughts of breaking 5 hours faded as I stopped for the bathroom three times, with the first two being +5 minute stops. Just didn't feel like standing back up and getting back to it. First 10 miles went pretty good, with splits of 11:16, 10:42, 10:47, 10:58, 10:31, 11:11, 11:03, a .1 mile lap to get back on the mile markers at a 1:22 pace, 10:49, 11:41 and 11:09. I then had a 20:00 mile with a 8 or 9 minute pit stop, then miles of 11:09, 11:08, 11:22, 11:31 and 11:38. Mile 17 was another bathroom stop with a 17:56 mile, then .16 miles at 15:39 pace to get back on the mile markers.The final 9.2 miles were a grind, I was walking about half a mile, then running a half mile. Splits were 12:30, 12:30, 12:18, 12:12, 11:59, 13:20 (quick bathroom stop), 12:35, 12:37 and 12:12. The final .27 miles to the finish were at a 10:24 pace. Overall 5:23:28, a 12:20 pace, AHR of 145. Though it was colder at the start, the sun was out and it felt pretty pleasant out. Was fun, will do it again some day, but would not want to make it an every year thing, that's for sure. Would plan better next time.
